A Simple Method for Evaluating Whole-Plant Cold Hardiness

Whole-plant assessment is direct, requires a minimum of equipment and expertise, and provides a good approximation of actual cold hardiness. Potted test plants are subjected to several target temperatures in a slightly modified domestic chest freezer. After gradual warmup, the plants are placed in a favorable growing environment for 7 to 14 days, and then the percent of cambial damage is determined. The temperature at which 50 percent damage occurs is determined graphically. Tree Planter's Notes 38(2):16-18; 1987.
